Statistically, the one time sex notion is true as long as the woman hasn't been 'conditioned' to the one time partner's DNA by, for example, extensive oral sex. (I can offer you references if need be). In this case if Gianna is fertile then, because of their history, the odds are very high that Carlito would impregnate Gianna.
Can you please make a second part one day ? I personally feel like this could be turned into a two parter
... with them knowing that they were going to fuck the entire time from the moment that she walked into the room.
As much as I love incest stories, I'm not a fan of pregnancy between bro/sis, mom/son, or dad/ daughter relationships. There's to much of a chance of producing a child with deformities that it will have to live with an entire lifetime.
Still a tender story.
I saw on your profile that you may in the future write a sequel to this story. I hope you give that some thought since this was a very good story with really engaging characters and an interesting dynamic that really could be expanded upon if you wanted. I look forward to reading the rest of your work!
